DIRIGIBLE HIEA.DLIGHT.

T0 all whom it mag concem:

Be it known that I, 0m E. MITCHELL a citizen of th United States, residing at Los Angeles, in the county of Los Angeles and State of California, haveinvented a new and useful Dirigi ble Headlight, ofwhich the followi ng is a specificatiom 1 This invention relates to dirigible headlights for vehicles, and has particular refererice po meai1s for ebntrolling the projecting ra.ys issuing from a. headlight.

The main object of this invention is to providea vehicle headlight which mayfbe turned to throw its light in either a straight 01 a lateral line, as maybe desired, and is esipecially adaptable for use in connectioxi with railway bars, launches, boats, aubomobiles, and other motive-power vehicles.

Another objectof this invention is to prov ide means for accomplishing these ende, which are devoid o! the usua.l cumbersome patts, a nd which are easily assembled and placed together, while at the same time pre- A serving its durability, practicality 'nd simplicity.

With these and other objeets in view, tl1e invention coi1sistsin the features' details of construction} and combinations of parts, as will be described in connection with the accompanying drawings, a.nd then be more partimiulrly pointed out in thelaims.

In the drawings, Figure 1 shows a rear end elevation of a headlight supportedin its biiurcation, the con trolling means being shdwn in section. Fig. 2 is a. vertica.l section through a fragment of one of the supporting arms for the headlight, the cup and a. fragment of the.lamp, theinterior 0f said cup being shown in full lines excepc the member 13. Fig. 3 is a top plan view with the cover re'moved. Fig. 4 is a detail of the stem which is arranged to be fastened so the lamp proper.

Referring more in detail t0 the (irawing, 1 represiants a headlight prope'r, provided with trunnions 2, which trunnions are carried by a prong 0r bifurcation 3. The headlight, as will be seen is so mounted as to be pivotally inclined in either one directionor the other, and

the stem 4 of the bifurcation is seated in a socket5 provided in the cup 6, which} in turn, is mounted upon a bracket 7 or upon the dash-boardof the vehicle. Said socket 5 has a tubular sleeve 5 having a rectangulaz: opening and forming a socket for the reception of the stem 4. The sleeve is made integral with a short lever er arm 8, which lever extends t0 the edge of the annular cup 6. Coiled aiound said tubulatr sleeve is a spring 9 having it;s respective ende 10 and 11 extending away from the body portion of the convolute, und bent upon itself at substantially right angles a.nd forming tanga. These tangs exten lvertically with respectto the cup 6 and are arranged to impinge against the arm 8 on eitlier side thereof, the tendency of the spring bein g-t o forcesaid tangs' toward one another. From the errange- 1nent as shown, it is obvious that by moving the arm 8 eith'er bo;the right or to t.he leih, it will carry with it one Specificatin nf Letters Patent.

tang of sa.id spring 9, and vice versa when the arm is foreed' Y in the other direction, tlie te11dency always being to' bring said arm in a straight-ahead position. Now in order to maintai'n 01ietang ofsaid spring in its normal position while the other is being moved againsi; its tension by the arm 8, I provide a block 12 which is 10- cated-intermediate the tang, which block is screwed o1 otherwise secured in .the cup 6. Thus, as the arm is moved towards the' right thel left tang will rema.in sta tionary while the tension of the right tang is being exejrted, und vice versa.

- The arm 8 provided in the cup is arrangedto ti'avel about a q1iartiar of the circum.ferenceof tl1e cup in either direct-ion1and in order 130 keep the Iespective tangs in positioi1ivhen theyare carried around to this quarter manipulationby band, in-order to bring said headlighb back into ite normal positio n;which is straight ahead, is obviated, the spring itself' -carrying with it. tl 1e arm 9 parforming this fimotion.

A Cover 14 is arrang d to fit on the cup 6, the said 'cover haviixg a conical extension-lmade integral Witl i said cover 14 -Said coni cal eiict'exision has likewise a rectangular opening correspondingio that of the socket', arid is anangedio allow the Stern 40f the bifurcation to pass theretliroqgh, Through the periphery of said cone o1 conical projection 15 extends a thumb-screw 14, which is arranged to engage saidstem 4 0f the bifurcation -3, and if any desired positiori other thini the normal position of tl1e headlight is desi red 1:0 clamp it against movement from that position.

A cuix 6 similar to cup. 6 is arranged to be secured to one arm of the bifufcation 3 in a vertical position. "It

is provided with a. tubular sleeve 52 having a rectangular hre 53, which sleeve is loose in said cup 6 Said s'lkeeve 52 is provided with an integral-mm 81 and ex tends vertically downward irisaid cup 6. T0 the side of said arm 81 is a helical spring 91 coiled about the tu-' bulat sleei e 52, the respec'tive ende of said spring extending away from the body f ortion 0f the convolute and bei1t upon themselves at right angles, as seen a|i 10 and 11 Said ende are hold spac'ed by a block 12' a.gainst which theybear. When the headlight is tilted either upwardly 01' downwardly, the arm 81 engages either of the spring ends l0 andll und carries with it one or the other of said end s against che tension oi the helix 9], and according to .the direction of movement; of the headlight. The releaLse of the headlight .1 causes the automatic retum of the same to ita normal osition.

- 130 extinguish..

1.3 is an elliptical member interpsed between Said arm and block and serves tq guide said arm as well as to prevent the dislocation of the spring ende 10 and 11. 41

is a eisern fitting the rectangular bore 53 0f the sleeve 52 and arranged to engage the conically-shaped body 18 which in secured to the body proper of the lamp 01 headthe control of the support in a plane perpendicular to .its axis independent of that oi the headlight.

The thumb-screw 14 extends thrmlgh lahe walls of said conical piece and engages on'e wall 0f the rectangular stem 4, which prevents flfe Iamp ironi turning ein its pivot points, and whieh is further designed to level the lamp m case the ja.r from the vehicle Carrying die same ha fored it out of a straightline; conseqently causing the light, provided it be an arc light, to falde or perhaps It is, of conrse, understood that the lamp a s represented and described in gonnection withits support, is not limited to any particular kind of lam-p; tha.t is to say, the mea;ns for producing the light is mit limited po acetylene, gas, or electricity, all ofwhich may be used in connection with my arrangement.

.ln tangs extending at rlght angles to the body 015 the spring, a block for keeping said tangs spaced, a llever integrally unlted wlth said sleeve and .extendlng between sald tangs, an elllptical mlember lnterposed between said lever and block for guidlng sald lever, and means for securing said suppo'rt. in lts adjusted posltlon.

2. The combinatlon with a support and means for pivotally mounting sald support, comprislng a eup, a tubular sleeve in sald eup provided with a rectangular bore ar= ranged to reeelve the stem o1 the support, a spring coiled about sald tubular sleeve and havlng lts ends terminatlng in tangs extending at rlght ungles to the body 013 the spllng, ablock for keeplng sald tangs spac eda lever integrally unlted wlth s'al'd sleeve und extending between sald tangs, an elliptical member lnterposed betweeu said lever and block tor guldlng said lever, means for plvotally mountlng a headllght in sald support comprlslng a eup secured in one arm of said support, having sprlng-actated n'xenns for governing the -movement of the headlight, and means for securlng sald headlight In its adjusted positlon.
